Force and Motion Worksheet
force is exerted on a 1000kg car accelerating at a rate of 15m/s2?
motion of a 12 kg object is opposed by a 30N force of friction.
At what rate does friction slow the object down?
asked to design a winding mountain road. What
force must you try to increase in designing this road?
How might you do this?
A 4 g
bowling ball rolling at 6 m/s collides head-on with an identical, motionless
bowling ball. If the first ball is
moving forward at 2m/s right after the collision, what is the speed and
direction of the second ball?
has no atmosphere and its gravity is about one-sixth as strong as that of Earth.
Considering these factors, how would the motions of objects near the moon
be different from the same motions near Earth?
weightlifter raises a 440 kg barbell with an acceleration of 2 m/s2.
How much force does the weightlifter exert on the barbell?
softball is larger and more massive then a baseball. Use Newton’s second law to explain why players can’t
throw or hit a softball as far as a
force is needed to accelerate a 85 kg rider and her 400 kg motorcycle at 3m/s2?
a force of 3000N to accelerate an empty 1000kg car at 3 m/s2.
If a 160 kg wrestler is inside the car, how much force will be needed to
produce the same acceleration?
A 63 kg
skater pushes off from a wall with a force of 300N.
What is the skater’s acceleration?
force is needed to accelerate a 1000kg car at a rate of 3 m/s2?
If a 70
kg swimmer pushes off a pool wall with a force of 250N, what rate will the
swimmer accelerate from the wall?
weightlifter accelerates a 200kg barbell with an acceleration of 3m/s2.
How much force does the weightlifter use to raise the barbell?
lifts his partner above his head with an acceleration of 2m/s2.The
dancer exerts a force of 200N. What
is the mass of the partner?
Newton’s second law of motion state?
factors affect the rate of acceleration of an object?
rate does gravity cause objects to accelerate?
