Find the force acting on a 14 kg wagon that produces an
acceleration of 1.5m/s2
A cat pushes a 0.25 kg toy with a net force of 8 N. According
to Newton’s second law what is the acceleration of the ball?
Kate applied a force of 10N on a tennis ball that was moving
at a rate of 12m/s2. What is the mass of the tennis ball?
Round to the nearest hundredth.
Station 2
Friction and Net Force
Calculate the net forces for the following examples and state whether they are balanced or unbalanced forces.
Directions. For each picture, draw an arrow to show the direction of the frictional force. Then name the type
of friction – static, sliding, or fluid – that is acting in each case.

Station 3: COLLISIONS
1. A collision occurs between two moving cars. What is the velocity of each car AFTER the
collision?
Before Collision
7 m/s
3 m/s
On your paper determine the velocity of the
vehicles after the collision.
2. A collision occurs between two cars that connect. What is the acceleration of each car AFTER the collision?
Before Collision
12 m/s
0 m/s
On your paper determine the velocity of the
vehicles after the collision.
3. A collision occurs between one moving car. What is the acceleration of each car after the
collision?
Before Collision
16 m/s
0 m/s
On your paper determine the velocity of the
vehicles after the collision.
4.
What is the momentum of a 12 kg bicycle moving at 5.5 m/s downhill? Show all work!
Station 4: WHICH LAW
Directions. Match each scenario with one of Newton’s Laws of
Motion.
 Write the number 1 for Newton’s 1st Law
 Write the number 2 for Newton’s 2nd Law
 Write the number 3 for Newton’s 3rd Law
1.A magician pulls a tablecloth out from under dishes and glasses on a table without
disturbing them.
2.A person’s body is thrown outward as a car rounds a curve on a highway.
3.Rockets are launched into space using jet propulsion where exhaust accelerates out from
the rocket and the rocket accelerates in an opposite direction.
4.A person not wearing a seatbelt flies through a car window when someone slams on the
breaks because the person’s body wants to remain in continuous motion even when
the car stops.
5.Pushing a child on a swing is easier than pushing an adult on the same swing, because the
adult has more inertia.
6.A soccer ball accelerates more than a bowling ball when thrown with the same force.
7. A soccer player kicks a ball with their foot and their toes are left stinging.
8. A student leaves a pencil on a desk and the pencil stays in the same spot until another
student picks it up.

Newton’s 2nd Law Relationships
1. If Cathy had a mass of 72kg and traveled to the moon which has a
gravitational acceleration of 1.6m/s2. Identify what her mass and weight would
be on the moon. Show all work!
2. A teenager is buying their first car. They choose to purchase a car rather than
an SUV because it gets more miles to the gallon when driving at the same
acceleration.
Force: ______________ Mass: _______________ Acceleration: _________________
What is the relationship between mass and force? ____________
3. You have a friend who has a smaller mass than you, but they walk exerting
the same amount of force as you. Why does your friend move faster than
you?
Force: _______________ Mass: _______________ Acceleration: _______________
